HYDRANT.

SPECIFICATION forming part of Letters Patent N o. 660,721, dated. October 30, 1900.

Application led March 31, 1900. Serial. N0. 3.0;876. (N0 model.)

To all whom` t may con/cern.-

Be it known that I, Erl-Ins CRoNsTEDT, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Hydrants, of which the following is a specification.

My invention relates to improvements in hydrants, its object being particularly to provide improvements in the actuating means for the cut-o device for the discharge-openings; and it consists in the features of construction and combination hereinafter specifically described and claimed.

In the accompanying drawings, forming part of this specication, Figure 1 is a partial side elevation of a hydrant fitted with my improvements. Fig. 2 is a top elevation thereof, partly broken away. Fig. 3 is a vertical section of the hydrant through the cutoff device, and Fig. 4 is a section taken on line a; of Fig. 3.

In the drawings, A represents the casing or body of the hydrant, provided with lateral discharge-openings 2 and 3, closed by caps 4.

B represents a valve-cylinder fitting within the casing A and formed with a horizontal opening 5, which is adapted to be brought into registering position with the passages 2 and 3. This cylinder is supported upon a circumferential iiange 6 upon the interior of the casing A and is operated by a gear 7, meshing with the teeth 8, arranged around the upper edge of the valve-cylinder. The gear 7 is provided with a shaft 9, passing upward through a stuffing-box 10 in a transverse wall 11 and through a stuffing-box 12 upon the top of the hydrant, the upper end of the 'shaft being squared to receive an operating-wrench. A rod 13 projects downwardly through the center of the hydrant to the main gate. (Not shown.) A stufng-box 14 is provided to prevent the waterl passing to the space above the wall 11, and the upper end 15 of the rod is squared to receive a wrench.

It will be seen that the wall 1 1 prevents water passing to the space above, the stuffingboxes 10 and 14 preventing water passing around the shafts 9 and 13, respectively. By having an internal gear meshing with teeth around the cut-off actuated by a rod passing upward through the wall 11 and top of the hydrant a particularly effective construction is obtained, which has many advantages over other actuating means I claim- 1. In a hydrant, the combination with its outer Wall or casing provided with dischargeopenings, of a cutoff device arranged within said hydrant for opening and closing said openings, a wall arranged across the hydrant above said device, teeth carried by said device, a gear meshing with said teeth, and a shaft carried by said gear and extending upward through the said wall and through the top of the hydrant.

2. In a hydrant, the combination with its outer wall or casing provided with dischargepassages,of a rotatable cut-off device arranged within said casing for opening and closing said passages, a wall arranged across the casing above said device, gear-teeth arranged around the upper edge of said cut-off device, an internal gear mes-hing with said teeth, and a shaft carried by said gear, passing upward through said wall and through the top of the hydrant.

3. In a hydrant, the combination with its outer wall or Vcasing having discharge-passages, of arotary cut-off device arranged within said casing for opening and closing said passages, a transverse wall arranged above said cut-0E device, preventing the passage of water to the space above said wall, teeth carried by said device, a gear meshing with said teeth, and a shaft carried by said gear and passing through a stuffing-box in said wall and projecting through the top of the hydrant.

In testimony whereof I aiiix my signature in presence of two witnesses.

ELIAS CRONSTEDT.
